Kind of like my old car in winter.
Fix leak, run engine, shut engine down, inspect for any evidence of additional leaking. Repeat as necessary.
Not to good to have a running jet engine when you need to poke your head inside to see if you fixed the leak. It is always nice to have your system operating and up to operating pressure, but sometimes you cant due to safety concerns of the mechanic.
